A Texas-sized block of iceThe first dedicated Antarctic Icepod mission was flown out across the center of the Ross Ice Shelf. Ice shelves are thick floating extensions of the ice sheet that form as the ice flows off the continent and into the surrounding ocean. These are critical ice features in Antarctica, bounding a full 44% of her coastline, where they serve as a buttress to slow the ice movement off the continent into the ocean.http://phys.org/news336993812.html

For the first time, an international team of scientists provide a comprehensive estimate on the full range of Antarctica's potential contribution to global sea level rise based on physical computer simulations. Led by the Potsdam Institute for Climate Impact Research, the study combines a whole set of state-of-the-art climate models and observational data with various ice models.http://phys.org/news327206837.html

In their paper published in the journal Nature, the team describes how they set up sensors to measure the impact of waves on sea ice and how their findings might help explain why sea ice is increasing in some parts of the world and decreasing in others.http://phys.org/news320569952.html

EarthThu, 27 Feb 2014 11:00:01 ESTnews312719462Disappearing snow increases risk of collapsing ice shelves in AntarcticaA number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover. Their collapse would enhance the discharge of ice into the oceans and increase the rate at which sea-level rises. A rapid reduction of greenhouse gas emissions could save a number of these ice shelves, researchers at Utrecht University and the British Antarctic Survey say in a new paper published today in the Journal of Glaciology.http://phys.org/news310226679.html

The discovery, involving cold, extra salty water - brine - that forms within openings in sea ice, adds to our understanding of how ice sheets interact with the ocean, and may improve our ability to forecast and prepare for future sea level rise.http://phys.org/news305533860.html

EarthThu, 21 Jun 2012 13:31:06 ESTnews259504259Climate scientists discover new weak point of the Antarctic ice sheetThe Filchner-Ronne Ice Shelf fringing the Weddell Sea, Antarctica, may start to melt rapidly in this century and no longer act as a barrier for ice streams draining the Antarctic Ice Sheet. These predictions are made by climate researchers of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association in the coming issue of the journal Nature. They refute the widespread assumption that ice shelves in the Weddell Sea would not be affected by the direct influences of global warming due to the peripheral location of the Sea.http://phys.org/news255780408.html
EarthWed, 09 May 2012 13:00:01 ESTnews255780408Study finds warm ocean currents cause majority of ice loss from AntarcticaReporting this week in the journal Nature, an international team of scientists led by British Antarctic Survey (BAS) has established that warm ocean currents are the dominant cause of recent ice loss from Antarctica. New techniques have been used to differentiate, for the first time, between the two known causes of melting ice shelves - warm ocean currents attacking the underside, and warm air melting from above. This finding brings scientists a step closer to providing reliable projections of future sea-level rise.http://phys.org/news254577590.html
